just yesterday I read that a researcher named "Giam Polo Goliani" (not sure about the spelling) has predicted an Earthquake in Italy and sent messages online telling people of his predictions that he based on some vibrations in the Earth, the officials denied it but then an earthquake did happen resulting in the death of more than 100 people (100 is the official number but people say it's 300+)
so I was wondering, what do yo guys know about the subject???
